The plot is a copy of “Zentangle art” by Stoshi – see her blog page here: Stoshi’s Blog
( I got her permission to post the image as long as she got the credit she deserves. )
She called the image “La Bella”, a great work of art! I traced the image by hand in Inkscape to get a SVG file.

It is a nice test as the plot consists of a lot of small line segments causing a lot of pen-up/downs and moves. Takes about half an hour to plot. As you see I have ‘elongated’ the image somewhat to improve resolution. Will try to improve resolution further by smooting the egg surface. Right now the ‘rough’ surface causes the ‘jagged’ lines.
